Justin Bieber has really taken to communing with nature during his trip to Boston.
The 22-year-old singer, who has spent the last several days in Boston while traveling across the country on his Purpose World Tour, was spotting sitting in a big tree in Boston Public Garden on Wednesday listening to music through his headphones and silently rocking out.

Bieber went as incognito as he could, wearing a great sweatshirt, denim cutoffs and black knee-high socks. He completed the low-key ensemble with black shades and a dark ball cap.
People passing by in the park who noticed the pop icon's presence in the foliage couldn't get enough of the unusual scene, and marveled at Bieber's tranquil serenity.

The public display of arboreal contemplation isn't the first time the "Sorry" singer has raised eyebrows during his visit to Puritan City. On Monday, Bieber was spotted walking through the city barefoot and attempting to feed the squirrels in the public park.
On Tuesday, Bieber went on an Instagram rant, demanding that people stop accosting him in public and declaring that he will no longer take impromptu photos with fans.
"If you happen to see me out somewhere know that I’m not gonna take a picture. I’m done taking pictures," Bieber wrote. "It has gotten to the point that people won’t even say hi to me or recognize me as a human. I feel like a zoo animal, and I wanna be able to to keep my sanity."

Perhaps he's found his happy place: alone with his music, cradled by the powerful boughs of a mighty oak tree (in a public park).
